' Original application illed July 10, 1924, Serial No. 725,177. Divided and this application iiled January Y 88,1926. Serial No. 84,808.

This invention relates, generally, to im-A provements in cartoning machines; and the same has reference, more particularly,l to mechanism for lining cartons preparatory to filling the saine; this application being a division of our co-pending application, Serial No. l725,177, filed July 10th, 19241for cartoning'machines. The present invention has for its pr1n cipal object to provide a novel means for pre-forming a sealed lining having an open outer end and inserting the same'in a carton preparatory to filling the latter. To this end the invention comprises a means to suplf-ply wax or paraiiine paper in combination with a forming mechanism adapted to preform a paper lining, closed at one or its inner end and open atjits other or outerend, while at the same time heating the wax or paraiiine which impregnates the lining paper to cause the laps and folds thereof to adhere together, to thus seal the lining, whereupon. the mechanism operates -to insert the preformed and sealed lining into a`carton'pre- 25 sented for its reception. d

Other objects of this invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description of the same.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the paper lining forming and inserting mechanism together with the means for supplying. paper thereto; Figure 2 is an enlarged detail plan view (with cover plate removed) of the wax paper lining forming and. inserting mechanism; Figure 3 is a longitudinal v ertical section through the same, taken on line 3 3 in said Figure 2; Fi lure 4 is a fragmentary lon itudinal vertical sect1on,vsimi lar to thats own in Figure 3, but showing the manner of forming the wax paper lining on the plunger or mandrel; Figures 5, 6 andl 7 are respectively fragmentary cross sections taken on the section lines 5-5, 6-6, and v7 7 in said Figure 3, but with Athe plunger shown as advancing the wax paper through the liningforming devices; and Figure 8 is a perspective view of a preformed or completed lining. Y Fig. -9 is an open end viewof ya carton as positioned to y'receive a linin said view showing the operation of the evice for spreading the side tabs of said carton.

Similar characters of reference are employed in all of the hereinabove described views, to indicate corresponding parts.

Referring now to said drawings, the reference character`41 indicates a carton Slideway upon which 'squared cartons closed at one end are moved into lining receiving position. Cooperating with said carton slideway l 41 is a keeper plate 42 for retaining the cartons against upward displacement, and arranged on the outer lon itudinal marginal portion of said carton slideway 41 is a stop flange 120, against which the closed end of,

ton slideway and lining mechanism is mounted. Su ported from said platform 7, so as to lie ush with vand extend transversel toward the inner longitudinal margin o said carton slideway 41, are supportingplates 121 u n which are mounted the lining forming evices, spaced apart to provide a mandrel pass e in which moves a transversely reciproca 1e.. plun er or mandrel 122, which moves in a gui e 123', being suitably actuated by an oscillating lever 124; to the lfree end of which issuitably interconnected the rear endof said plunger or mandrel, the oscillations of which produce properly timed forward and retractive movements of said plun er or mandrel. The forward operative en of said plunger or mandrel is heated by means of electrical heating ,elements12`5, which are embedded therein to respectively lie adjacent to the sides of said plunger or mandrel. Said plunger or mandrel is rovided with a central longitudinal air con uit or passage 126 open at its rearward end to the atmosphere, and terminating at the forward extremity of said plunger or mandreh The lining forming devices comblocks 127 mounted prisea pair of tucking upon the supporting p atesr 121 one on each side of the entrance end of said mandrel v passage. Said tucking blocks are provided.

v paper to b e employed in the formation of the carton lining. Mounted upon the supplates 121 beyond said tucking locks 12 are bottom folders or up-turning folder members 130, the inner vertical faces v131 of which are alined respectively with the faces 129 of said tucking members 128.

' Said up-,turning folder members 130 are provided with upwardl and forwardly inclined edges 132 which form fold-turning guides faced toward the'leading end of the plunger or mandrel '122. Also mounted upon the su porting plates 1.21 beyond said up-turning older members 130 are top folders or down-turning folder members 133, the inner vertical faces 134 of which are alined res ectively with the vertical faces 129 of5 sai up-turning folder members 130 and the vertical faces 129 of said tucking members 128. Said down-turning folder members 133 are of greater width than the up-turmn folder members 130 and are provided wit downwardly and orwardl inclined end ortions 135 which form fol -turning guides aced toward the leading end of the plunger or mandrel 122. Supported upon said su porting dplates 121, and in contact with t e outer s1 e faces of said down-turning folder members 133, are heater housing members 136, which are provided with internal chambers 137, in which are housed electric heating elements 138, which serve to generate and transmit heat to said down-turning folder members 133. Suitably supported, so as to bridge the plunger or mandrel passage intermediate the respective laterally opposed tucking and folding devices above described,- is a cover late 139. i

A suitab e means for supplying wax lining paper for manipulation by the plunger or mandrel 122 and the tucking and folding devices is provided. This means may be of any desired construction. which will serve to introduce a sheet of wax lining paper intermediate the retracted plunger or mandrel 122 and the tucking and folding devices. It is preferable to supply the wax lining paper, of a predetermined proper width, from a roll, from which the paper is automatically withdrawn and fed into place in front of the plunger or mandrel 122, and then severed to produce a separate sheet of desired length. The mechanism, as shown the drawings, for thus feeding the wax limng paper comprises, a suitable frame-work 140 mounted upon the platform 'Ilabove the plunger or mandrel and the devices. The framewith a forwardly protucking and folding' work 140 is provide jecting bracket 141 for supporting s indle on which is mounted, for free rotation, the reel 142 upon which a supply of wax lining paper 143 is wound. Mounted in the upper end of said frame-work 140 are 4continuously runnin inter-geared feed ously driven by a chain and sprocket drive 145, The paper 1passes from said continuously running rol ers 144 to a counter-poised take up roller 146 carried by a swinging frame 147, which is pivoted by supporting arms 140 connected with said frame-work` 140. This arrangement forms a loop of the paper intermediate said continuously running rollers 144 and a air of intergeared intermittently actuated eed rollers 148 which feed the* paper, in timed relation to the reciprocal movements of the plunger or manthe l 'rollers 144 which draw t e paper off of the supply roll. Said rollers 144 are continudrel, so that the same passes downwardly in front of the leading end of said plunger or mandrel 122, when the latter is retracted.

Said feed rollers 14S-'are actuated by a pawl`A and ratchet transmission 149, the operations of which are produced by pivoted lever 150,

which is interconnected therewith by a link Suitable power transmission means actuates a vertically reciprocable connecting rod 152, the latter being pivotall connectedl with the outer free vend of sai lever 150,

whereby the latter is oscillated to produce prredetermined length of paper is severed om the main run thereof by a horizontally oscillated shear blade 153, the timed operation of which is produced by suitable ower transmission means which oscillates a ever 155 suitably interconnected by a link 154 with the shear blade 153.

As thecarton moves into position to receive the lining, the longitudinally projectin side tab 2, at the forward or left-hand s i e of the carton body, springs past a sta- `t1onary tab spreader lug or finger 156, which 1s secured to and projects from the outer end of the right-hand down-turning folder member 133, but the side tab 2 at the rearward or ri ht-hand side of the carton body 1s arrested y engagement with said stationary tab spreader or finger 156. so as to be bentor sprung outward whereby the same is slightly deflected from the path of the plunger or mandrel 122 .as it carries forward and enters into the carton interior the preformed lining for insertion within the latter roper length of luc liu

(see Figure 2). A means is also provided for deflecting the forward or left-hand side tab 2 after the carton is alined with the p aper lining forming' and inserting mechamsm.

This latter means comprises a vertically oscillatable lever 157, which is fulcrumed on a post 158 mounted on the outer margin of said carton slideway 41. Suitable means (not shown) for producing properly timed oscillations of said lever 157 may be connected with the outer end 159 of said lever. Fixed on the inner free end of said lever 157 is a downwardly projecting spreader lug or linger 160, which possesses a cham-A fered free end 160. When the carton is alined in lining receiving position, 'and as the vplunger or mandrel 122 with the preformed lining thereon .approaches the Open end of the carton to insert the lining thereinto, the lever 157 is oscillated, by its timed actuating means, to swing downwardly the spreader lug or finger 160 into engagement with the left-hand or forward side tab 2, to thereby spread or deflect or wedge the same outwardly or away from the approaching plunger or mandrel and the lining carried thereby. V( See Figs. 1 and 9).

In operation, while the plunger or mandrel 122 is in retracted position, the paper feed mechanism delivers intermediate the plunger or mandrel and the tucking and folding devices a properly sized portion of the wax paper 143 (see Figures 2 and v3). The paper having been thu-s delivered, the advancing movement of the plunger or mandrel 122 is initiated by its timed actuating means, while at the same time the portion of paper delivered is sheared or cut away from the main run thereof. The advancing movement of the plungery or mandrel 122 carries the several paper sheets against the lower lip 161 formed by the adjacent end margins of the supporting plates 121 and the upper lip 162 formed by the adjacent end margin of theocover plate 139, whereby,

Cpl

as the p unger or mandrel. enters the passage, bounded on the 4sides by the tucking and folding devices, and respectivelyat the bottom and top by the supporting plates 121 and cover plate 139, the upwardly and downwardly extending portions of the papers are folded or doubled back upon the lunger or mandrel, so as to lie respectively at against the top and bottom surfaces/of said plunger or mandrel.. Since the width of the paper is greater than the width of the plun er or mandrel, longitudinal marginal and fo dable portions of the same-will be left projectin from each side of the plunger or mandre, at the top and bottom thereof. AsI the plunger or mandrel Vcarries the paper inwardly between the tucking blocks 127, the opposing ends of the T-shaped tucking members 128 will engage the laterally project-- of the plunger or mandrel.

ing portions of the fold of paper which is turned around the leadin end of the plunger or mandrel, and wil force or tuck such portions backwardly against the sides As such portions of the paper are turned and passed between the vertical end faces 129 of said T-shaped tucking members 128 and the sides 0f the plunger or mandrel, while the longitudinal marginal and foldable portions projecting from each side of the plunger or mandrel, at the top and bottom thereof, will be substantially undisturbed and will respectively "pass between top edges 128 of the T- shaped tucking members 128 and the cover plate 139, and between the bottom edges 128 of the T-shaped tucking member 128 and the supporting plates 121 '(see Figure 5). It isv preferable that :the respective to and bottom edges 128 and 128" of the T-s aped tucking members 128, shall slightly converge in a direction `opposed to the entering plunger or'mandrel, so that n0 undue strains are exerted upon the paper when producing the tucking' folds. As the plunger or mandrel continues to advance the longitudinal marginal or foldable portions of the paper projecting beyond the bottom surface of the -plunger or mandrel are carried into engagement with the up-turning folder members 130, the upwardly and forwardly inclined edges 132 of which engage 'and turn `upwardly said foldable portions of the paper, so that the same pass between the sides of the plunger or mandrel and the vertical face 131 of said up-turning folder members 130 (see Figure 6). As the plunger or mandrel further advances, the longitudinal marginal or foldable portions of thev paper projecting beyond the top surface of the plunger or mandrel are carried into engagement with the`down-turnin0' folder members 133, the downwardly and forwardly inclined end portions 135 of which engage vand turn downwardly said latter foldable portions, so that the same pass between the sides of the plunger or mandrel and the vertical faces 134 of said down-turning, folder members 133, while at the same time vcausing' the down-turned foldsV to overlap the previously formed upturned folds of the paper (see Figures 4 and 7), thus completing the` formation of a lining ready for lnsertion within the carton alined to receive the same.

vIt is desirable in many instances, especially when the lined cartons are to contain a product. the keeping qualities of' which are enhanced if protected from the atmos` phere, to hermetically seal the lining. T o this end a wax lor paraffin paper. isy rovided for the formation of theY lining, the wax or parallin saturating the paper being readily fusible at comparatively low temperatures. When, therefore, a lining is formed by the movement of the plunger or mandrel through the tucking and folding devices, a proper a plication of heat will fuse the wax or para and will cause overlapping and interfolded parts of the lining to adhere together, and will thus hermetically seal the joints formed at such overlappin and interfolded parts. It, has, hereto ore,r been quite .the common practice in forming such 'ealed linings to heat the plunger or mandrel, but when the latter is theonly source of o r means for applying the heat, the sealing results are not always uniform orV certain, especially in a @comparatively high speed machine, such as the present invention seeks to provide. We have in the instant invention provided in addition to the heated mandrel, a means -for heating the downturning. folder members 133, so that as the overlapped longitudinal folds of the lining are brought together, the wax or parailin in each fold is independently supplied with fusing heat, so that immediately on contact one with the other the softened or melted wax or arailin of'r one fold will at once fuse with) the softened or melted wax or paraffin' of vthe other fold, whereby a uniform imion throu hout their areas of mutual d, and the adjacency of a -cold surface toone fold tending to nonuniform fusion of the contacting folds is avoided. This feature of our linlng forming mechanism is deemed of considerable importance both as to novelty and utility. The nlining havingv been preformed and hermetically sealed in the manner above indicated, the plunger or mandrel, as it continues to advance, carries the lining onward and through the opposdopen end of the awaiting carton, so'as to insert the same into the interior of the latter. The lining having thus been entered in the carton, the retractive movement of the plunger or mandrel withdraws the latter leaving the lining in place within the carton. In orderto revent the withdrawing plun er or man el from effecting a suctlon ten ing to displace the lining from its operative vinserted position, lthe plunger or mandrel is provided with an air passage 126, as above mentioned, so that air may enter the interior of the lined carton as the plunger or mandrel is displaced. Another factor which operates to prevent displacement of the lining from the carton as the plunger or mandrel withdraws, comprises a pair .of carton pressure blocks which respectively engage the under side of the carton and the upper side of the carton, whereby the comparatively cold walls of the carton are pressed against the hot wax paper of the inserted lining to thereby cause the wax to congeal and adhere to said carton walls, thus holding the inserted lining4 against outward displacement. The said carton pressure blocks comprise, a lowerV pressure block, 163 which is mounted upon a leaf slpring 164 adapted t0 press the same up-A ward y through an opening in the carton slide-way 41 into engagement with the underside of the carton, and an upper pressure block 165, which is mounted .upon a leafspring 166, secured to said keeper plate 42, and adapted to press the same downwardly against the upper side of the carton (see Fig. ures 2 and 3).

After the sealed lining, has beeninserted in the carton, the forward movement of a succeeding carton, upon the cai'ton slideway, into position to in turn receive its lin1ng,` engages and pushes onward the former carton, wherebyv theV lining mechanism functions in connection with a succession of cartons fed to the same.

0f course, we are aware, that our inven tion is capable of some changes in the general arrangements and combinations of the various devices and parts as set forth in the foregoing specification, and as defined in the clauses of the claims which are appended thereto. Hence, we do not limit our present invention to the exact arrangements and combinations of the various devices and parts, as described in the said specification,
